Specification of Letters Patent.

Patented Oct. 16, 1906.

Application filed December 2, 1905- Serial No. 289,965.

To all whom, it Wmy concern:

Be it known that I, SAMUEL H. LUCAS, a citizen of the United States, residing at New Brunswick, in the county of Middlesex and State of New Jersey, have invented certain new and useful Improvements .in Locomotive Ash-Pans, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to locomotive ashpans, and more may be dumped while the engine is in motion, one of the objects being to provide a device of the character described which shall be simple and comparatively inexpensive in construction, durable and efiicient in operation, and which can be attached to any locomotive.

With these and other objects in view the invention resides in the construction and combination of parts hereinafter more fully described, particularly pointed out in the claim, and illustrated in the accompanying drawings, in which Figure 1 is a side elevation of the rear portion of a locomotive with parts broken away and showing the ash-pan closed. Fig. 2 is a similar view showing the ash-pan open. Fig. 3 is an end view of a locomotive, showing the device mounted thereon and Fig. 4 is a perspective view of the device detached.

Like reference-numerals designate corresponding parts in all the figures of the drawings.

1 represents the rear portion of a locomotive-boiler, and 2 an arcuate or curved bracket the ends of which are bent to form double right angles and provided with openings 3, whereby they are secured to the locomotive-boiler by bolts or other suitable means, said bracket being bent in the manner shown in order to leave an open space between the boiler and the greater portion of the bracket for the free passage of a bellcrank lever 4,having a handle 5, by which it is operated, said bell-crank lever being slidably mounted on the bracket by means of a transverse opening 6 therein. Passing into the lever at the outer side opposite the bracket is a threaded opening 7, adapted to receive a set-screw 8, the inner end of which engages with the bracket and holds said lever in any adjusted position on the bracket. This lever is pivotally mounted on the boiler, as shown at 8, and its lower end pivotally connected with an arm or link 9, pivoted 0n particularly to those which a projecting lug or stem 11, fixed on the boiler. The other arm of said bell-crank lever is pivotally connected with a plurality of leaves or shutters ,12 by means of a crankarm 13, which forms a pivotal connection be tween the belLcrank lever rality of crank-arms 14, which crank-arms are all pivotally connected with each other by means of a horizontal bar 15. Each crank-arm .14is fixed on a rock-shaft 16, passing through an ash-pan l7 and being suitably jo'urnaled in bearings in its sides. I As shown in Figs. 1 and 2, the rock-shafts are journaled between the bottomsof the side wall of the ash-pan and bearing-plates secured thereon. Each rock-shaft 16 has fixed thereon one of said leaves or shutters 12, and

there may be as many shafts, crank-arms, and shutters as may be found expedient or desirable. The leaves or shutters 12 when in closed position, as shown in Fig. 1, form the floor or bottom of the ash-pan 17, and it is upon this floor that the ashes accumulate as they sift through the grate-bar 18. As shown in Fig. 1, the longitudinal edges of these leaves or shutter-plates overlap when in closed position, and the two endmost ones engage stop-shoulders, formed at the bottoms of the front and rear walls of the ashpan.

In operation, the shutters or leaves being in closed position, as shown in Fig. 1, the setscrew 8 is turned until its inner end is released from contact with the arcuate or curved bracket 2. The handle 5 of the bellcrank-shaped lever 4 is pushed toward the front of the locomotive. This causes the short arm 19 of said lever to rise and carry with it the link or arm 9, which throws into operation the bell-crank lever 10, causing its lower arm (designated by 20) to move forward, pushing the link or arm 13 with it. This link or arm being pivoted on one of the crank-arms 14 imparts forward movement tosaid crank-arm, and this crank-arm being connected with all the others by the horizontal bar 15 imparts to each of them like forward movement. Each of the crank-arms being fixed on the shaft 16, each shaft is caused to rock, and the leaves or shutters 12 are thrown into vertical position, as shown in Figs. 2 and 4. A reverse movement of the handle 5 causes reverse action of all the parts heretofore mentioned and closes the shutters, whereupon the lever 4 can again be one arm of the bell-crank lever 10, carried by and one of a plu locked on the bracket 2 by means of the setscrew.

From the foregoing description it is believed the construction and operation of my device will be clearly and readily understood, and further explanation is not deemed necessary.

Having thus described my said invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

The combination of the fire-box and the ash-pan, of a locomotive-boiler, said ash-pan being of rectangular form with an open lower end and stop-shoulders on its front and rear walls, bearing-plates secured upon the bottom edges of the side Walls of the ash-pan, transverse rock shafts journaled between said bearing-plates and the sidewalls of the ash-pan, shuttenplates fixed on said rockshafts and arranged to overlap each other in closed position to provide a floor or bottom for the ash-pan, the endmost plates being adapted to engage the stop-shoulders on the front and rear walls of the ash-box, a crankarm fixed upon the projecting outer end of each of the rock-shafts, a bar pivotally connected to each of the crank-arms, a fixed pivot-stud projecting from one side of said fire-box, a bell-crank pivoted upon said stud, a link connecting onearm of the bell-crank to one end of said bar, a second pivot-stud projecting from said side of the fire-box, a second bell-crank pivoted upon the last-mentioned stud, a link connecting the short arm of the second bell-crank to the other arm of the first-mentioned bell-crank, the long arm of the second bell-crank being formed to provide a handle and havin an enlargement formed with a transverse slot and a threaded opening, an arcuate bracket spaced from and fixed upon said side of the fire-box and passing through the slot in the enlargement of the handle whereby the latter travels thereon, and a set-screw in the threaded opening in the enlargement of the handle and impinging against the said bracket, whereby the handle is held in adjusted position there on, substantially as shown and for the purposes set forth.

In testimony whereof I hereunto affix my signature in presence of two witnesses.

SAMUEL H. LUCAS.
